Title: Transmission line twin frequency terminal connection - uses transformation sections to transform impedances within given range
Inventor: BRUGER PETER DR
IPC: H01P5/04
Filed: 1980-07-19
Abstract: The method of forming a terminal connection for a high frequency supply line is used when two transmission frequencies are used with a common wide band aerial. A transformation system divides a section of the line into two transformation members. These members permit frequency adjustment and have different impedances for two given frequencies, these impedances lying within a limited range, and are used to transform at the same time these impedances into two other impedances also within a limited range. The second impedances match the characteristic impedances of the line sections. These two line sections are connected to a further set of sections with further frequency adjustment within further limited ranges, expressed by a set of formulae.
